Hi,
     In my flash had the following code.
import flash.events.TextEvent;
tf.addEventListener(TextEvent.TEXT_INPUT, tfHandler);
function tfHandler(e:TextEvent):void{
    trace(e.target.text.length);
    if(e.target.text.length == 2){
        e.target.appendText("-");
        stage.focus = tf;
        tf.setSelection(tf.text.length,tf.text.length);
     Like this How to do in AS2.?
Thanks with,

Use:
tf.onChanged = function(){
    if(tf.length == 3){
       tf.text += "-";
       Selection.setSelection(tf.text.length, tf.text.length);
